As shown in FIGS. 1 to 3, a film packing device 100 according to a preferred embodiment of the present invention comprises a handle 10 and a film packing unit 20.
The handle 10 has a first connection rod 11 and a second connection rod 12 at two lateral ends thereof. The first connection rod 11 has a first positioning hole 111 and a first fixing hole 112 thereon. The second connection rod 12 has a second positioning hole 121 corresponding in position to the first positioning hole 111 and a second fixing hole 122 corresponding in positioning to the first fixing hole 112.
The film packing unit 20 is disposed between the first connection rod 11 and the second connection rod 12. The film packing unit 20 comprises an axle tube 21, a first rolling member 22, a quick-release member 23, a second rolling member 24, and a pivot member 25.
The axle tube 21 can be formed in one-piece or composed of a plurality of sleeves 211 which are connected one by one, as shown in FIG. 3. Each sleeve 211 has a first positioning portion 211 at one end thereof and a second positioning portion 213 at an opposing end thereof. With the first positioning portion 212 and the second positioning portion 213, the sleeves 211 are connected together to form the axle tube 21. Two ends of the axle tube 21 are formed with the first positioning portion 212 and the second positioning portion 213, respectively. In this embodiment, the first positioning portion 212 is a protruding ring. The first positioning portion 212 has a positioning block 214 on an outer surface thereof. The second positioning portion 213 is a trough. The second positioning portion 213 has a limit groove 215 on an inner wall thereof to connect with the first positioning portion 212. Each sleeve 211 further includes three tightening pieces 216 thereon, so that the axle tube 21 has a number of tightening pieces 216 thereon.
Referring to FIG. 4, one end of the first rolling member 22 has a first connecting portion 221 corresponding to the first positioning portion 212 of the axle tube 21. The first connecting portion 221 is a trough. The first connecting portion 221 has a positioning groove 222 thereon to connect with the first positioning portion 212 of the axle tube 21. The other end of the first rolling member 22 has a protruding ring 223 corresponding to the first positioning hole 111 of the handle 10. The protruding ring 223 has two slots 224 thereon. The quick-release member 23 is disposed in the protruding ring 223. The quick-release member 23 includes a fixing rod 231 and a spring 232 which is located between a bottom of the protruding ring 223 and the fixing rod 231. One end of the fixing rod 231, opposite to the spring 232, is extended out the protruding ring 223 by the spring 232 and inserted in the first positioning hole 111, such that the first rolling member 22 is pivotally connected to the first connection rod 11. The fixing rod 231 has two limit levers 233 at two sides thereof corresponding to the two slots 224 for the user to apply force.
Referring to FIG. 5, one end of the second rolling member 24 has a second connecting portion 241 corresponding to the second positioning portion 213 of the axle tube 21. The second connecting portion 241 is a protruding ring. The second connecting portion 241 has a limit block 242 thereon to connect with the second positioning portion 213 of the axle tube 21. The other end of the second rolling member 24 has a circular trough 243 to connect with the pivot member 25. The pivot member 25 includes a pivot block 251 received in the circular trough 243. The pivot block 251 is rotatable in the circular trough 243. The pivot block 251 has a threaded hole 252 for insertion of a pivot rod 253. One end of the pivot rod 253, opposite to the pivot block 251, is provided with a stop block 254 and inserted in the second positioning hole 121, such that the second rolling member 24 is pivotally connected to the second connection rod 12.
In addition, the film packing device 100 further comprises a roller unit 30 which is disposed between the first connection rod 11 and the second connection rod 12. The roller unit 30 has two rollers 31. Two ends of each of the rollers 31 are provided with gears 32 to mesh with each other, so that the rollers 31 are driven to rotate. An outer side of the gears 32 is provided with a casing 33. One end of the casing 33 is provided with a connection shaft 34 to be inserted in the first fixing hole 112 of the first connection rod 11 and the second fixing hole 122 of the second connection rod 12, respectively. The casing 33 close to the second rolling member 24 has one side formed with an extension portion 331. The extension portion 331 has a guide groove 332 thereon. The guide groove 332 is connected between the pivot block 251 and the stop block 254 of the pivot member 25 to confine the turning of the roller unit 30.
FIG. 6 and FIG. 7 are schematic views showing the present invention when in use. When the user wants to use the film packing device 100, a roll of film 200 which does not have a reel therein is mounted in the film packing device 100. As shown in FIG. 4, the user pulls the limit levers 233 of the quick-release member 23 to pull up the fixing rod 231 towards the axle tube 21, so that the fixing rod 231 disengages from the first positioning hole 111 of the first connection rod 11. The film packing unit 20 is taken out from the handle 10, and then the first rolling member 22 is disengaged from the axle tube 21. As shown in FIG. 7, the roll of film 200 is fitted on the axle tube 21 with the fastening pieces 216 to prop the roll of film 200, achieving a support effect. The first rolling member 22 is then connected to the axle tube 21. As shown in FIG. 5, the pivot block 251 of the pivot member 25 is inserted in the circular trough 243 of the second rolling member 24. As shown in FIG. 4, the fixing rod 231 of the quick-release member 23 is secured in the first positioning hole 111 of the first connection rod 11, such that the roller of film 200 is mounted on the film packing device 100. As shown in FIG. 7, the user uses the film packing device 100 of the present invention to pack an object 300 in a quick, simple and convenient way.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
